FLORA is Adafruit’s fully-featured wearable electronics platform. It’s a round, sewable, Arduino-compatible microcontroller designed to empower amazing wearables projects.
It’s small 1.75″ diameter, weighing 4.4 grams and has the best stainless steel threads, sensors, GPS modules and chainable LED NeoPixels, perfect accessories for the FLORA main board.
The FLORA has built-in USB support and USB HID support, so it can act like a mouse or keyboard to attach directly to computers. The power supply is designed to be flexible and easy to use. There is an onboard polarized 2 JST battery connector with protection schottky diode for use with external battery packs from 3.5v to 16v DC in. Can be used with LiIon/LiPoly, LiFe, alkaline or rechargeable NiMh/NiCad batteries of any size.
FLORA has onboard power switch connected to 2A power FET for safe and efficient battery on/off control. It has an onboard 3.3v 250mA regulator with a protection diode and USB fuse so that the microcontroller voltage is consistent and can power common 3.3v modules and sensors.
The power system is specifically designed to allow easy control and power of a large quantity of addressable NeoPixels. Flora can easily drive 50 pixels directly from the onboard power supply, or up to 500 with the pixels externally powered by a separate 5V supply.
FLORA is fabric friendly, all the components on board are flush to the PCB and won’t snag delicate garments.
The FLORA has 4 indicator LEDs: power good, digital signal LED for bootloader feedback, data rx/tx. Also onboard is an ICSP connector for easy reprograming for advanced users.
There are 14 sewing tap pads for attachment and electrical connections. Data buses are interleaved with power and ground pads for easy module and sensor attachments without worrying about overlapping traces which are not possible with conductive thread.
